Chandra X - ray Observations of NGC 1316 ( Fornax A )
2 Abstract We report the results of the Chandra ACIS sub-arcsecond resolution X-ray observation of the archetypal merger radio galaxy NGC 1316 (Fornax A). We confirm the presence of fine sub-structures in the hot Interstellar Medium (ISM). Some of these are likely to result from interaction with the radio jets, while others may be related to a complex intermingling of different phases of the IS...
متن کاملTelescope Planetary Camera Images of NGC 1316 ( Fornax A ) 1
We present HST Planetary Camera V and I band images of the central region of the peculiar giant elliptical galaxy NGC 1316. These high resolution Based on observations with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by AURA, Inc., under NASA Contract No. NAS 5-26555. The National Optical Astronomy Observatories are operated by the A...
متن کاملAtomic and molecular gas in the merger galaxy NGC 1316 ( Fornax A ) and its environment
We present and interpret observations of atomic and molecular gas toward the southern elliptical galaxy NGC 1316 (Fornax A), a strong double-lobe radio source with a disturbed optical morphology that includes numerous shells and loops. The CO(1–0), CO(2–1), and Hi observations were made with SEST and the VLA. CO emission corresponding to a total molecular hydrogen mass of ∼5×10 M⊙ was detected ...
متن کاملThe Curious Case of NGC 6908 1
The object NGC 6908 was once thought to be simply a surface-brightness enhancement in the eastern spiral arm of the nearby spiral galaxy NGC 6907. Based on an examination of near-infrared imaging, the object is shown in fact to be a lenticular S0(6/7) galaxy hidden in the optical glare of the disk and spiral structure of the larger galaxy. New radial velocities of NGC 6908 (3,060 ± 16 (emission...
متن کاملMeasurements of the Field and Particle Energy Distributions in the West Lobe of the Radio Galaxy NGC 1316 ( Fornax A )
A follow-up X-ray study was made of the west lobe of the radio galaxy Fornax A, (NGC 1316) based on new ASCA observations made in 1997 for 98 ks, and incorporating the previous observation in 1994 for 39 ks. The 0.7–10 keV spectrum of the emission can be described by a power-law of energy index 0.74 ± 0.10, which agrees with the synchrotron radio index of 0.9 ± 0.2. Therefore, the X-rays are re...
